  1. 1. RFID TECHNOLOGY WONG YIU TING 1220072717 October 2012
  2. 2. FutureIntroduction Survey development Application Conclusion of RFID results and opportunities
  3. 3. RFID RFID = Radio Frequency Identification Electronic labeling and wireless identification of objects using radio frequency Tag carries with its information  a serial number  Model number  Color or any other imaginable data When these tags pass through a field generated by a compatible reader, they transmit this information back to the reader, thereby identifying the object
  4. 4. RFID COMPONENTS A basic RFID system consists of these components:  A programmable RFID tag/inlay for storing item data;  Consistingof an RFID chip for data storage  an antenna to facilitate communication with the RFID chip A reader/antenna system to interrogate the RFID inlay Application software and a host computer system
  5. 5. RFID TAG The RFID tag consists of an integrated circuit (IC) embedded in a thin film medium. Information stored in the memory of the RFID chip is transmitted by the antenna circuit embedded in the RFID inlay via radio frequencies, to an RFID reader 3 types  Passive  Semi-passive  Active
  6. 6. TYPES OF RFID TAGS Active Tags Semi-passive Tags Passive Tags• Use a battery • Contain built-in • Derive their power• communicate over batteries to power from the field distances of several the chip’s circuitry, generated by the meters resist interference reader and circumvent a • without having an lack of power from active transmitter to the reader signal transfer the due to long distance. information stored • They are different from active tags in that they only transmit data at the time a response is received
  7. 7. APPLICATIONSFrequency Appx. Read Data Speed Cost of Tags Application RangeLow <5cm Low high -AnimalFrequency (passive) -Identification(125kHz) Access ControlHigh 10 cm – 1m Low to Medium to Low -Smart CardsFrequency (passive) Moderate -Payment(13.56 Mhz) (paywave)Ultra High 3m -7m Moderate to Low -Logistics andFrequency (passive) High Supply Chain(433, 868-928 -BaggageMhz) TrackingMicrowave 10m -15m High High -Electronic toll(2.45 & 5.8 (passive) collectionGhz) 20m – 40m (Autotoll) (active) -Container Tracking
  8. 8. CURRENT APPLICATIONS Application Representative Competitive Current Penetration Typical Tag Type Segment Applications Technologies Access Control Doorway entry Other keyless entry High Passive technologies Asset Tracking Locating tractors None Low Active within a freight yard Asset Tagging Tracking corporate Bar Code Low Passive computing systems Authentication Luxury goods Holograms Low Passive counterfeit prevention Baggage Tracking Positive bag matching Bar Code, Optical Low Passive Character Recognition POS Applications SpeedPass Credit Cards, Smart Medium Passive Cards, Wireless Phones SCM (Container Tracking containers in GPS-based Systems Low Active Level) shipping terminals SCM (Pallet Level) Tracking palletized Bar Code Minimal Active, Passive shipments SCM (Item Level) Identifying individual Bar Code Minimal Passive items Vehicle Identification Electronic toll Bar Code, License Medium Active, Passive collection plate, reader systems Vehicle Immobilizers Automotive ignition Other theft prevention High Passive systems technologies
  9. 9. Credit Cards with RFID(Paywave function) APPLICATIONS Octopus (Smart Card)
  10. 10. Autotoll (Electronic toll collection) APPLICATIONS Access Control
  11. 11. ONLINE SURVEY Target: SME Information: Opinion on RFID and its applications Site:  http://qtrial.qualtrics.com/SE/?SID=SV_9N5UPR ZuyuWtsk4
  12. 12. SURVEY RESULT types of companies answering the questionnaire 12% 6% 6% 23% Education Manufacturing Retailing Warehousing Transportation Others 29% 24%
  13. 13. FURTHER DEVELOPMENT In medical uses and library management
  14. 14. VIDEO
  15. 15. CONCLUSION Positive  RFID is a contactless reading technology and can read through other materials  Hold more data than barcode does  RFID tags data can be changed or added  More effective, bring lots of convenience to us Negative  Cost is relatively remain high (compare to barcode)  RFID signals may have problems with some materials  RFID standards are still being developed
